The present invention discloses gene targets, constructs and methods for the genetic control of plant disease caused by nematodes of the genus Meloidogyne (root knot nematodes). The present invention relates to achieving a plant protective effect through the identification of target coding sequences and the use of recombinant DNA technologies for post-transcriptionally repressing or inhibiting expression of the target coding sequences in the cells of plant-parasitic nematodes. The disclosed gene targets show significant conservation at the nucleotide level between orthologs from different Meloidogyne species, facilitating genus-wide targeting by RNA interference. La présente invention concerne des cibles géniques, des constructions et procédés pour le contrôle génétique de maladies végétales provoquées par des nématodes du genre Méloidogyne (nématodes cédidogènes). L'invention concerne l'obtention d'un effet de protection de végétaux par l'identification de séquences de codage de cible et l'utilisation de technologies d'ADN de recombinaison pour une répression ou inhibition de manière post-transcription de l'expression des séquences de codage de cible dans les cellules de nématodes parasites de végétaux. Les cibles géniques décrites présentent une conservation importante au niveau nucléotidique entre des orthologues par rapport à des espèces de Méloidogyne différentes, facilitant un ciblage large en fonction du genre par interférence d'ARN.
